Students gain an understanding of the factors that affect wind turbine operation. Following the steps of the engineering design process, engineering teams use simple materials (cardboard and wooden dowels) to build and test their own turbine blade prototypes with the objective of maximizing electrical power output for a hypothetical situation—helping scientists power their electrical devices while doing research on a remote island. Teams explore how blade size, shape, weight and rotation interact to achieve maximal performance, and relate the power generated to energy consumed on a scale that is relevant to them in daily life. A PowerPoint® presentation, worksheet and post-activity test are provided.

This applet from Statistical Java allows the user to generate bivariate data for analysis with simple linear regression. The page describes the equations used to generate the data and estimate the regression lines.

This lesson unit is intended to help you assess whether students recognize ...

This lesson unit is intended to help you assess whether students recognize relationships of direct proportion and how well they solve problems that involve proportional reasoning. In particular, it is intended to help you identify those students who: use inappropriate additive strategies in scaling problems, which have a multiplicative structure; rely on piecemeal and inefficient strategies such as doubling, halving, and decomposition, and have not developed a single multiplier strategy for solving proportionality problems; and see multiplication as making numbers bigger, and division as making numbers smaller.

This lesson takes the learner through a series of exercises where the ability to understand ratios and calculate unit cost will help the learner make optimal, well-reasoned, cost-effective purchasing decisions. The target audience is the adult learner (preferably with school-age children) working in the Grade D range (6th-8th grade) and with RP Domain (Ratios and Proportional Relationships). Learners will benefit by seeing the relationship that mathematical concepts have to their everyday lives by using mathematical reasoning to make better purchasing decisions. Mastery of this material will help learners demonstrate readiness for higher-level algebraic concepts.

This lesson unit is intended to help students judge the accuracy of ...

This lesson unit is intended to help students judge the accuracy of two different approximations to a particular linear relationship. Students will compare two linear functions as approximations to the relationship between Celsius and Fahrenheit temperature and consider under what circumstances each of the approximations may be reasonable.
